Setting Up 6 Flight Modes Using Flap and Elev D/R Switches For The Spektrum DX7s Radio

For those of you who have been attempting to get 6 flight modes out of your Spektrum radio, I have finally figured a method to make it work with the "Flap" and "Elev D/R" toggle switches. I won't bore you with details but attached are my instructions to reconfigure your radio (mine is a DX7s) to allow only one channel to be used to toggle up to 6 modes. I prefer to keep Channel 7 available for other things.

These are the values (PWM) I came up with

Elev D/R – 0                 Flap – 0                      Mission Planner – Flight Mode 6                PWM - 1932
                                                  1                                                                            3                              1395
                                                  2                                                                            1                              1136

Elev D/R – 1                 Flap – 0                      Mission Planner – Flight Mode 5                PWM - 1715
                                                  1                                                                            4                              1530
                                                  2                                                                            2                              1299

    Warren, please post you configuration file and I will look it over.

    I had a crack and got to here: http://diydrones.com/group/ardurover-user-group/forum/topics/gettin...

    I did exactly what you did - reviewed what other folks (namely you) used to setup their settings, then a lot of trial and error!!!

    MikeRover, I ran into the same snag with lack of supporting documentation on the Spektrum radio.  What I did do was review what other folks used to set up their settings and then a lot of trial and error.  I did connect my drone to the Mission Planner softer and as I adjusted mixing and trim settings, observe the affect on the Flight Mode menu.  Once tweaked, I then performed flight control checks then low altitude flight testing to ensure I had no crazy affects when switching modes.  Sorry that I am not able to help too much.  Good Luck.

    Is there any useful documentation anywhere on what all the Spektrum parameters mean?  This is cool, and I'll be implementing it, but I'd also like to play some more with driving spare Rover channels (elevator and aileron) with the D/R switches. 

     

    I got it setup last night so I can have elevator switch from -100% to +100% via the mix switch, and aileron from -100% to 0%, but that was more trial and error than anything else. The Spektrum manual is very basic.  Is there a "mix, trim and switch" tutorial somewhere?  How did you nut all this out?

    Oh nice, I've been mixing gear with flap for years to get 6 positions.  I've been running the knob on channel 6/7.  This is nicer, one more channel.

    I do not own one, but I'd say yes.  Recommend you backup your radio parameters for the wing you are flying then make the changes and test fly it.  If it doesn't configure and work for you, you can import you saved parameters over top the latest one and be back to what you have.  Please let me know if it works for you.

    For anyones interest, I ran 4 flights today and used all 6 modes with no ill affects. Very pleased with setup.

    Hi Scott,

    This article is different in that I wanted to not use my "Gear" toggle which is Channel 7 for mixing with my "Flap" toggle to achieve 6 flight modes (actually 5).  So this post is to provide those another option of using two co-located switches to achieve 6 flight modes on one channel (channel 5).
